Added Files:
        src/sbin/blkdiscard: Makefile blkdiscard.8 blkdiscard.c

Log Message:
convert my fdiscard-stuff.c into blkdiscard.c and give it a UI
that matches the linux-util version.

comes in two forms:  blkdiscard equivalent, and the (almost)
original interface i used (the "-s" option is conflicting and
i've switched to only the not yet implemented secure erase
option.)  the only real difference is that "fdiscard" mode
requires the -R flag to do something, vs blkdiscard needs the
-n flag to not do anything.

not yet hooked into the build or sets.  would like more testing
on it to be performed before doing that (but soon.)
